How to Use Claude Code: Install, First Session and What It Costs

Claude Code isn’t a chat window in your browser. It opens in your terminal, reads your project’s files on its own, edits them, runs the tests and commits. Say “fix that bug” and the expectation is that it finds the file and changes it. This guide walks the path from install to your first code change, and gives a straight answer on the free-version question 🧑‍💻 The Short Answer If you only have a minute Install (Windows PowerShell): irm https://claude.ai/install.ps1 | iex Install (macOS, Linux, WSL): curl -fsSL https://claude.ai/install.sh | bash Start it: cd into your project and type claude No free tier: you need a Claude subscription (Pro, Max, Team, Enterprise) or a prepaid Console account First move: run /init to generate a CLAUDE.md for the project What Is Claude Code? Claude Code is Anthropic’s coding agent for the terminal. What separates it from a regular AI assistant is that it doesn’t only produce text. It has tools for reading files, writing files, running commands and searching the web, and it decides on its own which to use and in what order. ...

Claude Code Slash Commands: The Complete List

Claude Code Slash Commands: The Complete List

The list that pops up when you hit / in Claude Code is intimidating at first. A hundred-odd commands, half of them named in a way that gives nothing away, and your own custom commands mixed in with the built-ins. You don’t need all of them. Ten commands cover almost everything you do day to day, and the rest is reference material you look up when the moment arrives. This page gives you both: the ten first, then the full list grouped by what it’s for 🧰 ...

What Is Qwen3.8-Max? The AI That Ran Alone for 125 Hours

What Is Qwen3.8-Max? The AI That Ran Alone for 125 Hours

Summary: Qwen3.8-Max in 30 Seconds Qwen3.8-Max is Alibaba’s new flagship model, made generally available on August 2, 2026. 2.4 trillion parameters, 95 billion active (MoE architecture). It reads text, images and video, and returns text. Context window is in the 1 million token class. On one task it ran 125 hours (about 5 days) with no human input, rebuilding an experiment from a machine learning paper from scratch, confirming its six findings, then inventing a method that beats the paper. It beats Claude Opus 4.8 on most coding and agent tests, trades blows with Claude Fable 5 and GPT-5.6 Sol, and falls behind on some. API pricing is $2 input / $6 output per million tokens. Repeated input costs $0.25. This is the first time Alibaba has open-weighted a Max-class model. The weights landed on Hugging Face on August 12, 2026, though under Alibaba’s own Qwen3.8-Max license rather than Apache 2.0. Two days later, on August 14, Qwen3.8-27B followed: a dense 27B model under Apache 2.0 that fits on a single GPU. Ask an AI to “rebuild the experiment in this paper, then improve on it” and it normally stalls after a few turns, waiting for you to step in and steer. ...

What Is MCP? Model Context Protocol Explained

What Is MCP? Model Context Protocol Explained

You want to tell an AI “read this file”, “pull that record from my database”, “close this issue”. The model cannot do any of it on its own, because it has no access to your machine, your database or your accounts. MCP exists to close exactly that gap. It puts a standard connection layer between the AI application and the outside world 🔌 What Is MCP? MCP (Model Context Protocol) is an open-source standard for connecting AI applications to external systems. ...

What Is Agentic AI and How Do AI Agents Work?

What Is Agentic AI and How Do AI Agents Work?

“Agentic AI” is the most-discussed term of 2026, and most of what gets written about it looks at the same angle: enterprise transformation, productivity gains, automated customer service. All true, and none of it answers the question a developer actually has: how does this thing work? This post takes that angle. How the loop turns, which component actually executes tool code, why memory became its own architectural layer in 2026, and where these systems break 🤖 ...
